Abstract
PARIS. Academy of Sciences, July 17.—Charles Moureu, Charles Dufraisse, and Marius Badoche: Autoxidation and antioxygen action. The catalytic properties of phosphorus compounds. Details of the antioxygen action of various compounds of phosphorus towards benzaldehyde, furfuraldehyde, and styrolene. Phosphoric acid and the phosphate slow down some oxidations in a very marked manner.—S. Winogradsky: The agronomic application of a microbiological test. A modification of the azobacter test is described, which indicates the lime and phosphoric acid requirements within 48 hours.—S. Drzewiecki: A theoretical interpretation of the experimental ballistic curve F(v)/v2.—Jean J. Trillat: A new method of. X-ray spectrography. Application to the study of the orientation of the fatty acids by mercury.—C. Marie and Mile. M. L. Claudel: The influence of the pH in the electrolytic deposit of copper in the presence of gelatine. It is known that when copper solutions containing gelatine in solution are electrolysed, the weight of the deposit is greater than that calculated from Faraday's law. This increase depends on the pH of the solution and is at a maximum for pH about 3.2.—A. Blanc: The photoelectric current as a function of the field and fatigue.—A. Morel, P. Preceptis, and A. Galy: The action of picric acid upon glycyl-glycine. This compound has been obtained in definite crystals, possessing the composition of a monoglycylglycine monopicrate. The crystallographic characters are given.—J. O. Haas and C. R. Hoffmann: Tertiary movements in the plain of Northern Alsace.—G. Nadson and N. Krassilnikov: Schizophytes of the caecum of the guineapig: Anabseniolum.—R. Dieuzeide: The evolutive cycle of Pemphigella follicularia.—R. Sazerac and H. Nakamura: The mechanism of the preventive action of bismuth against Spirochætaicterohemorrhagiæ.
